Loudspeaker Design for Smart Systems - Modelling, Measurement, Control

Digital signal processing used in active loudspeaker systems creates new degrees of freedom in the design of the Electroacoustical transducer to increase the efficiency and maximum output while decreasing size, weight and cost. Adaptive nonlinear control can compensate actively for loudspeaker nonlinearities and protect the transducer from mechanical and thermal overload. The seminar presents the theoretical basis for understanding the transducer in the small and large signal domain considering the modal vibration, the dominant nonlinearities inherent in loudspeakers and the heating process. The seminar makes the relationship between symptoms and physical causes of the distortion more transparent and addresses the perceptions of various signal distortion. 

Attendance is highly recommended for transducer and system engineers in the audio industry active in research and development, manufacturing and quality control.
